'Virtual Heat Treating' using DEFORM-HT
"Virtual Heat Treating" using DEFORM-HT
Keywords Heat treatment, Simulation, Software
"Virtual heat treating" with the new DEFORM™-HT simulation software claims to minimise trial-and-error in process development by predicting a wide range of part-specific metallurgical and physical properties including residual stress, distortion and hardness before manufacture. A new, stand-alone module of the DEFORM (Design Environment for FORMing) software system developed by Scientific Forming Technologies Corporation, Ohio, DEFORM-HT helps ensure product quality and performance, while significantly compressing time-to-market.
According to Wilde & Partners utilising advanced finite element methods, DEFORM-HT can model the most complex aspects of the heat treating process, including normalising, annealing, quenching, tempering, ageing and carburising. It can predict the distribution of hardness, volume fraction of metallic structure, distortion, stress/strain, and distribution of carbon in the carburising process all vital intelligence in developing optimum machining and finishing strategies.
Other new features claimed include a PC version of the full 3D metal forming simulation program, and a ductile fracture modelling capability for simulating processes such as chevron cracking, blanking and machining. The DEFORM System is widely used in both research and industrial applications to model demanding processes, such as forging, extrusion, heading, drawing, die stress and heat treatment. Other applications have included thermomechanical process development for aerospace and other metallurgically sensitive alloys in hot, warm and cold deformation processes.
